The JAM Pedals Red Muck Bass puts on a few pounds, grows a new set of sharp teeth and is out to seduce even the most demanding Muff connoisseurs! 

A fuzz distortion pedal, inspired from the circuits of the ’71 “triangle” and the later “Red Army / Civil War” Muff. Along with JAM Pedals individual touch, the end result boasts a smoother sound, fatter low end, pronounced midrange and added tonal flexibility through the expanded range of the tone knob.  The onboard MIX control allows you to discover your sweet spot of the Dry/Wet signal ratio, while the second footswitch turns it into a two gain stage fuzz pedal

The JAM Pedals Red Muck Bass is equally capable at fuzzing things up just a bit to add some vintage wooly fatness to your bass lines, as it is at shooting those heavy riffs into sizzling yet controlled mayhem.
